GSK-3β inhibitor 2 is primarily utilized in research and therapeutic contexts to study and modulate the activity of glycogen synthase kinase-3 beta (GSK-3β). This enzyme plays a critical role in various cellular processes, including metabolism, cell proliferation, and apoptosis. By inhibiting GSK-3β, this compound is used to investigate pathways involved in diseases such as Alzheimer's, diabetes, and cancer. It helps in understanding the molecular mechanisms underlying these conditions and in developing potential treatments. Additionally, it is employed in studies related to neuroprotection and the regulation of insulin signaling, making it a valuable tool in biomedical research.
